If you do have access to MATLAB: http://www.mathworks.com/
Create a schema for the file (i.e specify the format you want, the
dimensions, variables and attributes) using ncwriteschema.
You can reuse this schema in case you want to create multiple files:
http://www.mathworks.com/help/techdoc/ref/ncwriteschema.html
Read the data in using textscan.
Look at the 'HeaderLines' to skip over the comments.
http://www.mathworks.com/help/techdoc/ref/textscan.html
Write the data to the netcdf file using ncwrite.
http://www.mathworks.com/help/techdoc/ref/ncwrite.html
Depending on the size of your files and the memory available on your
machine, you could either use textscan/ncwrite to read in and write all
the data at one time,
or loop through line/N lines and use the 'start' option in ncwrite to
append the data in batches.

Do you use an analysis package such as R, IDL, or Matlab? Many such
packages
can create netcdf files. It might be easiest to read your files into a
package you are familiar with, then write the netcdf file in the package.

Hello,
I have been googleing to find a solution to convert a couple hundreds of
ASCII files to Netcdf however, the solutions I found don't really fit
into
my data set. So, I wanted to ask in here.
My ASCII files come from a GWC (generic water column) data. I paste the
header and first two lines of the data below;
/# -----------------------------------------------------
# Source Files Information
# Index Filename
# 0 I:\raw\234.all
# -----------------------------------------------------
# Field Definitions
# 0 Sample File ID (see above)
# 1 Sample Position X
# 2 Sample Position Y
# 3 Sample Position Z
# 4 Sample Value (Amplitude)
# 5 Sample Time
# 6 Sample Range
# 7 Ship Position X
# 8 Ship Position Y
# 9 Ship Heading (degs)
# 10 Ship Pitch (degs)
# 11 Ship Roll (degs)
# 12 Transducer Depth (m)
# 13 Sound Speed (m/s)
# 14 Ping Number X
# 15 Ping Time X
# 16 Sample Number X
# 17 Beam Number X
# 18 Beam Azimuth X
# 19 Beam Elevation X
#0 1 2 3 4 5 6 7

Any suggestions to convert this to netcdf? I installed ferret but
couldn't
manage to write the suitable code.
Thanks!
